Help wanted for non-mechanical (but quite handy) Freelander owner. No money, mechanical neighbour in hospital. Problem with Y-reg V6 Freelander. Research suggests cam sensor and says it's easy to change. Can someone confirm that it is (easy)? And point me to it - pic with an arrow would be great! I know it sounds thick, but I just need a few directions. Can't afford (and don't trust) main dealer.
